Eighteen centuries are 1800 years, then how can 18 centuries be completed till the year 1800 has expired? What is the meaning of a century, but a clear distinct series of 100 years? How can 100 be completed by 99?,

A centenary is the hundredth anniversary of some event. When your great grandfather turns 100, his birthday party will be the centenary of his birth. If your town is celebrating its centenary, that means it’s exactly 100 years old.

Is 2000 the last century?

For the 2,000th Time, the 21st Begins in 2001 I hesitate to write again about when the 20th Century ends, because I suspect that almost everyone who lives that long will be celebrating “the turn of the century” on the night of Dec.31, 1999, even though the century will not end for another year.

  1. The 21st Century will not begin until Jan.1, 2001.
  2. I have been surprised, though, by the number of letters I have received from readers who insist that the new century will begin (as most people seem to think) on Jan.1, 2000.
  3. Some of their letters are accompanied by ingenious but misleading graphs and tedious histories of our calendar’s origin, including abstruse arguments about the date of Christ’s birth and Western concepts of zero.

None of them seem to grasp the simple fact that 10 is 10, and after 10 comes 11. It takes 10 years to make a decade. It takes 100 years to make a century. The first decade ended on Dec.31, AD 10. The first century ended on Dec.31, AD 100. The second decade began on Jan.1, AD 11.

  • The second century began on Jan.1, AD 101.
  • Centuries always end in 00.
  • New centuries always begin in 01.
  • I’m asking you a large favor,” writes Fred A.
  • Glienna of South Pasadena.
  • Could you please deal in your column one more time with the start of the 21st Century?” He explained that he raised the question at a kaffeeklatsch of his model railroading club, and it was argued for more than an hour.

The next day he fired off several proofs of his position (the same as mine); one who had argued vociferously against him switched; another didn’t; a third, who had agreed with him, switched back. It is not stupidity that causes this misperception; it is some kind of rigid and unassailable mind-set.

I have exchanged three letters with a former Caltech professor, H. Victor Neher, who seems irretrievably stuck in his conviction that the century will end on Dec.31, 1999. His arguments are supported by irrelevant historical asides and illustrated by graphs that he heroically misinterprets. Like most of the heretics, he seems to be hung up on zero as a starting point.

“The first year of the first century begins at 0 and ends at 1. The 99th year then begins at 98 and runs until the beginning of 99. The 100th year begins at 99 and runs until the end of 99 or the beginning of the 100th year. This makes 100 years. There are 101 years between zero and 101, not 100 years.” Weird.

  1. The first year doesn’t end at 1; it ends at 2.
  2. The 99th year doesn’t run until the beginning of 99; it begins at the end of 98 and runs to the end of 99.
  3. The 100th year does not run to the end of 99, it runs to the end of 100, up to 101.
  4. How could it run to its own beginning? It’s really very simple.
  5. A century is 100 complete years.

So the first century ended on Dec.31, AD 100. That took it to the first day of the second century, Jan.1, AD 101. And so on to Jan.1, 2001. Don Ayers of Pacific Palisades argues reasonably that we think of the 20th Century as the 1900s. “While 1999 is clearly a part of this group of years, the year 2000 is clearly within the period to be referred to as the 20 hundreds, or the 2000’s, by future generations.” Of course.

  1. And that is the custom that will set off riotous celebrations on the night of Dec.31, 1999.
  2. The next day we will be in the 2000s, even though, in fact, the 20th Century has a year to go.
  3. I wonder, will 20th Century Fox change its name to 21st Century Fox a year early? Howard A.
  4. Wilcox of San Diego asks, sounding almost desperate, “Can you please forward to me an authoritative reference justifying your statement that the 20th Century began on Jan.1, 1901?” I quote the World Almanac and Book of Facts: “A century consists of 100 consecutive calendar years.

The first century consisted of the years 1 through 100. The 20th Century consists of the years 1901 through 2000 and will end Dec.31, 2000. The 21st Century will begin Jan.1, 2001.” I have an idea that Prof. Neher won’t switch. : For the 2,000th Time, the 21st Begins in 2001

Why is 2000 not the 21st century?

The numbering of years and calendrical reckoning has always been a controversial topic. The civil calendar used in most countries is also known as the Gregorian calendar. The initial epoch (first year) of the Common Era (CE) is 1 CE also known as AD 1.

The first century comprises the years AD 1 through AD 100. The second century began with AD 101 and continued through AD 200. By extrapolation, the 20th century comprises the years AD 1901-2000. Therefore, the 21st century began on 1 January 2001 and will continue through 31 December 2100. Similarly, the 1st millennium comprised the years AD 1-1000.

The 2nd millennium comprised the years AD 1001-2000. The 3rd millennium began with AD 2001 and will continue through AD 3000. Over recorded history, many initial epochs have been used for calendrical reckoning. Frequently, years were counted from the ascension of a ruler.

  • For a calendrical epoch to be useful, however, it must be tied to a sequence of recorded historical events.
  • The initial year of the Common Era was chosen to be first year to commence after the birth of Christ.
  • This is the initial epoch of the Julian and Gregorian calendars.
  • This epoch was established by the 6th century scholar Dionysius Exiguus who was compiling a table of dates of Easter.

Dionysius followed a previous precedent, extending an existing table (by Cyrillus) covering the period 228-247. This table was reckoned from the beginning of the reign of Emperor Diocletian. However, Dionysius did not want his Easter table “to perpetuate the memory of an impious persecutor of the Church, but preferred to count and denote the years from the Incarnation of our Lord Jesus Christ.” To accomplish this, he designated the years of his table Anni Domini Nostri Jesu Christi 532-550.

  • Thus, Dionysius’ Anno Domini 532 is equivalent to Anno Diocletiani 248, establishing a correspondence between the new Christian Era and an existing system associated with historical records.
  • Dionysius did not, however, establish an accurate date for the birth of Christ.
  • Scholars generally believe that Christ was born a few years before AD 1, but the records are too sketchy to allow a definitive dating.

How are dates prior to an initial epoch recorded? Today it appears obvious that a year designated 1 would be preceded by year 0, which would be preceded by year -1, etc. But the concept of both 0 and negative numbers did not come into common use in Europe until the 16th century.

  • Even then, these concepts were initially only of interest to mathematicians.
  • Their application to chronological problems did not occur for two more centuries.
  • Instead, years were counted using a succession of initial epochs.
  • Even as Dionysius’ practice of dating from the Incarnation became common in ecclesiastical writings of the middle ages, traditional dating practices continued for civil purposes.

In the 16th century, Joseph Justus Scaliger tried to resolve the patchwork historical eras by placing everything on a single system. Not being ready to deal with negative year counts, he sought an initial epoch in prior to any historical record. His approach was numerological and utilized three calendrical cycles:

the 28-year solar cycle, the 19-year Golden Number cycle, and the 15-year indiction cycle.

The solar cycle is the period after which week days and calendar dates repeat in the Julian calendar. The Golden Number cycle is the period after which moon phases repeat (approximately) on the same calendar dates. The indictions originally referred to the periodic reassessment for an agricultural or land tax in late third-century Roman Egypt.

  • Scaliger could characterize a year by the combination of numbers (S,G,I), where S runs from 1 through 28, G from 1 through 19, and I from 1 through 15.
  • A given combination will recur after 7980 (= 28 x 19 x 15) years.
  • He called this a Julian cycle because it was based on the Julian calendar.
  • Scaliger knew that the year of Christ’s birth (as determined by Dionysius Exiguus) is characterized by the number 9 of the solar cycle, by Golden Number 1, and by number 3 of the indiction cycle, or (9,1,3).

Scaliger chose as this initial epoch the year characterized by (1,1,1) and determined that (9,1,3) was year 4713 of his chronological era. John Herschel later adopted Scaliger’s initial epoch for the Julian Day numbers used by astronomers. We would say that Scaliger’s initial epoch was 4713 BC or -4712.

Are we in the 2000 century?

Why 2012 is in the 21st Century – We live in the 21st Century, that is, the 2000s. Similarly when we say “20th Century,” we are referring to the 1900s. All this because, according to the calendar we use, the 1st Century included the years 1-100 (there was no year zero), and the 2nd Century, the years 101-200.
